What a slab leak looks like
What people ask
Whose water is it if the Marana leak is in a common line?
We cannot say who is responsible. The technician tells you what they find and where, so you can take it to the right party. That holds across Marana, including ZIP codes 85653 and 85658.
Is a slab leak likely in a Marana home from this period?
It is possible. Homes of this age have been in service long enough for wear, and a high bill or warm floor is worth checking. That holds across Marana, including ZIP codes 85653 and 85658.
What is a pinhole leak in a Marana home?
A tiny break in the wall of a pipe that weeps slowly. Under a slab it can run for a long time before anything shows above. That holds across Marana, including ZIP codes 85653 and 85658.
Can you tell what my Marana home's pipes are made of?
We do not assume a material. In Marana homes built since the 1980s, the material is confirmed when the line is exposed.
Can drip irrigation raise my Marana bill?
Yes. Switch the controller off at its panel and read the meter again. If it stops moving at your Marana home, the water was going to the yard.
What does acoustic listening pick up in Marana?
It picks up the sound of water escaping a pressurized pipe, loudest nearest the break. In a Marana slab home that narrows a long line to a short stretch.
Why are the lines isolated first in a Marana home?
Knowing which line is losing water means searching a short stretch of pipe instead of the whole Marana house. It also keeps any opening in the slab small.
Are most homes in Marana on slabs?
Marana grew mostly in the 1980s, 1990s and 2000s, and nearly all of that housing sits on slabs. A good number of houses from these decades were remodeled once, which can change where the lines run.
Do you also cover Sahuarita and Green Valley?
Yes. Sahuarita and Green Valley are covered by the same crews. Call with the address and we confirm availability.
Where Marana fits
Marana stretches along Interstate 10 northwest of Tucson, from old farm fields near the Santa Cruz River to newer communities in the Tortolita foothills.
Slab leak repair and replacement in Marana
Most slab leak visits in Marana begin with a meter reading, not a tool. Marana had 51,904 residents at the 2020 Census. Marana grew mostly in the 1980s, 1990s and 2000s, and nearly all of that housing sits on slabs.
Lines from these years are middle-aged: past the early years, not yet as worn as the oldest tracts. Many homes are in associations, and townhomes and shared walls are part of the mix. The visit plan takes this into account.
Pools and irrigation are the usual answer to missing water in this area, so they are ruled out first. Rock and caliche in the ground slow some openings. It is useful to know this before anything is opened. A few minutes at the meter and the controller usually says whether the slab is involved.

Service lines and drip zones
Between the meter and the house there is usually a stretch of buried pipe, and many yards add drip lines on a timer. Either can leak into the dirt unseen, which raises the water bill without any dampness indoors.
For that reason the sprinkler and drip check goes first, ahead of anything under the floor.
Rerouting through walls and the attic
It avoids opening the floor and is often discussed when a line has leaked more than once.
A sound with everything off
The technician uses listening equipment to find where the sound is loudest along the line.
Proving the leak
It tells us which line, not exactly where, so it is followed by listening and thermal work.
Is it the slab, the yard or the pool?
No tools, just watching, and you end at whichever step settles it.
Four steps to the leak
Same-day visits are the aim.
Call for a QuoteWear from the inside
Older metal pipes with very hard water tend to develop pinholes. We deal with the leak itself, its location and the ways to fix it.
Options once it is found
What fits depends on the line and layout, and you approve it before work starts.
